The research was conducted on the ecological competition and soil environmental safety in the transgenic sugarcanes mediated with SrMV-P1 gene. Ecological competition is mainly reflected through the evaluation on the viabilities of sugarcanes exposed to water and low temperature stress. The soil environmental safety of the transgenic sugarcane mediated with SrMV-P1 gene was evaluated on the soil microorganism, conductivity, pH and soil enzyme activities on the continuous research of Yunxia Fu and Bixia Zhen...
